The inspector also interviewed eight other licensee employees during the course of this inspection, including health physics and chemistry technicians, members of the security force, and general office personnel.
General This inspection consisted of an examination of the licensee's non-radiological environmental protection, effluent control, and moni" toring programs; sampling techniques and analytical procedures; sampling locations and collection equipment; environmental program results; and an abnormal environmental occurrence in 1978.
The inspector utilized the licensee's Appendix B Technical Specifi-cations as amended, and Sections 3.3.3.4 and 4.3.3.4 of Appendix A Technical Specifications as the primary criteria for the inspection.
The licensee received a Technical Specifications change to Appendix B on November 8, 1978 from NRC and requested an additional change in March 1979 to terminate the ecological programs by January 1,
1981.
Abnormal Environmental Occurrence (AEO) Re ort 50-315/78"04 a
Review of AEO 78-04 (occurrence dated September 23, 1978) revealed that during the 1000 chlorination on September 23, 1978, the chlorine residuals at the condenser outlet were recorded as 0.10, 0.11, and 0.12 ppm at 1010, 1012, and 1015 hours0.0117 days <br />0.282 hours <br />0.00168 weeks <br />3.862075e-4 months <br />, respectively.
Samples prior to this time were averaging 0.04 to 0.06 ppm.
Licensee investigation revealed that the chlorine feedrate had increased from 750 lbs per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 1100 lbs per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, caused by clutch slippage of the feed rate control motor of the chlorinator.
The chlorinator was secured, the clutch tension adjusted, and the chlorinator tested to verify proper operatio The inspector discussed this problem with licensee representatives and found that the licensee 'has seldom used the chlorination system since this incident occurred.
This event represents noncompliance with Appendix B Technical Specification 2.2.1.2.
4.
Nonradiolo ical Environmental Monitorin Pro ram a
Mana ement Controls The inspector reviewed the licensee's administrative and proce-dural controls for implementation of the nonradiological environ-mental monitoring pry~ram.
This program has not changed since the last inspectio However, the water chemistry and circulating water temperature measurement programs are conducted by plant personnel.
b.
Circulatin Water Tem erature Differential Except under certain conditions, Technical Specification 2.1.1.2 limits the maximum condenser 6 T to 22
+ l F for Unit 1 and
0
+
1 F for Unit 2.
The inspector examined selected temperature strip charts and thermal analysis data sheets for 1978.
No problems were observed with these charts and sheets.
The inspector also observed the temperature strip chart recorders in the control room which are calibrated every 18 months.
The inspector also reviewed procedure THP 6040 PER.016 issued in January 23, 1979, as related to circulating water thermal analyses.
Thermal analyses were apparently made as required and the inspector identified no problems in this area.
c
~
Circulatin Water Chlorination Technical Specification 2.2.1.2 limits the total residual chlorine in the plant discharge to the lake to O.l ppm.
Selected chlorine analysis data taken during 1978 and the daily computer printout sheets which identify required analyses and samples to be taken on a day-to-day basis were reviewed by the inspector.
The computer identified days on which chlorination took place.
No major problems were found when the inspector compared the computer printout to the chlorine analyses data sheets.
The inspector observed the amperometric chlorine titrators during a tour of the plant, reviewed procedure THP6020 ZAB.008, dated March 14, 1979, and noted that the amperometric titrators used for chlorine analysis are calibrated every six months.
The inspector also visited the chlorine house to observe the chlorination system.
Except for the chlorine AEO discussed above, no outstanding problems were identified in this area.

IE Inspection Report No. 50-315/78-1 Other Chemical Dischar es to the Environment Technical Specification 4.1.1.6.2 limits the use of the corrosion and deposition inhibitors, primarily phosphate (heating boiler blowdown) and ammonium hydroxide, discharged in the all volatile treatment process for the steam generators.
The discharge of other chemicals such as sodium sulfate, boron, and detergents, is also limited in accordance with Technical Specification 4.1.1.7.2.
The inspector reviewed the actual quantities dis-charged in 1978 as reported in the 1978 Annual Environmental Operating Report and found no major problems in this area.
Abiotic Pro ram Thermal plume studies including wind and current measurements and scour studies are conducted by the licensee's contractor, Environmental Technology Assessments, Inc.
The licensee has not yet conducted the thermal plume studies since both units have not operated together at 75'j power or greater; however, the licensee expects to conduct the first thermal plume measure-ments in the third quarter of 1979.
The inspector reviewed the licensee's two scour studies conducted in 1978 and reported in the Annual Environmental Operating Report.
The inspector toured the sites where the studies using sounding techniques were conducted and found no outstanding problems.
The inspector also reviewed the licensee's erosion studies conducted by the University of Michigan and described in the licensee's Annual Environmental Operating Report, and determined that the studies were made as required by Technical Specification 4.1.1.3.
Review of the licensee's Annual Environmental Operating Report revealed that the licensee had conducted the chemical analysis of groundwater and lake water samples on a semi-annual basis as required by Technical Specification 4.1.1.5.
The inspector also observed the location of monitoring wells ll and 12 in the field.
The Technical Specifications change effective November 18, 1978, deleted the requirement to conduct static water level determinations and ground water analysis of samples taken from monitoring wells 2, 3, 6 and 7.
In addition, the change extended the requirement to monitor groundwater movements at the waste absorption field from yearly to two year intervals.
The inspector noted that the licensee had conducted this monitoring program in 1977.
The inspector has no further questions regarding this ite f.
Biotic Pro rams The inspector reviewed the 1978 Annual Environmental Operating Report for results of different surveys including zooplankton, phytoplankton, benthos, periphyton, fish, impingement and entrainment studies.
The inspector observed that confusion still exists with the University of Michigan contractor as to designation of sampling locations.
A licensee representative stated that attempts are being made to resolve this problem.
The inspector noted that required samples have apparently been taken.
In terms of underwater surveys, Technical Specification 4.1.2.1.4 requires that five dives are made each month, with one dive to be performed during the night, for the April - October period.
The inspector noted in the review of the 1978 Annual Environmental Operating Report that five dives were made during May, June, July, and September six dives in August, but only four during April and three dives in October.
The report stated that adverse weather conditions prevented completion of the sampling schedule.
(2)
Terrestrial Studies Review of the 1978 Annual Environmental Operating Report revealed that the terrestrial studies reported were for 1977 and none were reported for 1978.
The 1977 studies were not presented in the 1977 Annual Environmental Oper-ating Report.
Discussions with licensee representatives indicated that the licensee apparently conducted a very limited program in 1978.
A Technical Specifications change effective November 8, 1978, deleted the requirement for conducting the terrestrial program.
No items of noncompliance or deviations were identified.
5.
Licensee Internal Audits Discussion with a Quality Assurance Engineer indicated that an audit of the nonradiological programs had been conducted during 1978.
The Plant Nuclear Safety Review Committee reviews proposed changes to the Technical Specifications and investigates all violations of the Technical Specifications; and the Nuclear Safety and Design Review Committee (NSDRC) reviews and audits the chemistry and radiochemistry activities in these areas.
The inspector reviewed the NSDRC audit of the nonradiological environmental monitoring program conducted on
- 5-
August 8-9, 1979.
The audit identified two major problems.
One dealt with the need to update Procedure THP 6040 PER
.045 on peri-phyton sampling techniques and the second, the need to report the terrestrial monitoring program results in a timely basis.
The first problem was resolved on September 19, 1978 and the second one was resolved by reporting the 1977 terrestrial study results in the 1978 Annual Environmental Operating Report as discussed in Paragraph 4.f(2) above.
No items of noncompliance or deviations were identified.
6.
Meteorolo ical Monitorin Pro ram The inspector reviewed meteorological data contained in radioactive effluent release reports dated January 1 - June 30, 1978, and July 1, 1978 through December 30, 1978.
The licensee checks the recorders for operability on a daily basis (except weekends)
and adjusts them if necessary.
The licensee's contractor, Meteorological Evaluation Service, Incorporated reviews the charts from the recorders and reports the information to the licensee.
The inspector reviewed Procedure 12THP6030
+ MP.034, Revision 4, dated April 24, 1979,
"Meteorological Instrumentation Calibration",
and determined that recorders and instruments are calibrated every six months by Control and Instrumentation personnel.
No problems were identified in this area.
7.
Exit Interview The inspector met with licensee representatives (denoted in Paragraph 1 above) at the conclusion of the inspection on June 15, 1979.
The inspector summarized the scope and findings of the inspection and discussed the above item of noncompliance.
